Exactly. There is no such thing as an purely unbiased news organization. I think CNN honestly tries to believe and act as if it were unbiased, though it definitely has a liberal tilt. Fox and MSNBC are perhaps smarter in that they have given up even trying, and won market share in so doing. Everyone on this planet has bias. Every producer, every reporter, every program director. Real journalists do their best to push that bias down and make it nothing, but now and again, it will always rear it's ugly head.
So you do admit when one company owns 70% of the news (Murdoch in Australia) they may have some kind of advantage then?
Hardly something I would call an advantage especially when all it takes is a call from the White House to pull an entertainer's decade old Monday Night Football opening from the evenings events; permanently.
